I tried to calculate the relative molecular mass for the below: could someone check for me please if got it right

5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene dihydrobromide dihydrate, trans-[14]-diene = 430 g mol^-1

5,7,7,12,14,14-hexamethyl-1,4,8,11-tetra-azacyclotetradeca-4,11-diene) copper(II)bromide = 491.37 g mol^-1
